Input Variable





The fraction of the sulfur in the fuel that gets emitted as particulate matter. HOMER assumes that the rest gets emitted as sulfur dioxide. This value is 2.2% for diesel generators, according to the EPA document EPA420-P-02-016, dated November 2002, entitled "Exhaust and Crankcase Emission Factors for Nonroad Engine Modeling -- Compression-Ignition".

HOMER uses this value to calculate the emissions of sulfur dioxide. Note that HOMER does not use this value this value to calculate emissions of particulate matter. For that, it uses the particulate matter emissions factor. For details, see the article on How HOMER Calculates Emissions.
